COMBINED, TRIMMING- AND. GHANNELING MACHINE.

Patented March 2, 1909.

To all whom it mayconcern:

Be it known that I, WILLIAM E. SMALL, a citizen of the United States, residing in -Brooklyn, in the county of Kings and State of New York, .have invented a new and useful Improvement in a Combined Trimming and Channeling Machine, of which the following is a specification.

, This invention relates to a device for trininiing and channeling shoe soles and the object of the invenbionis a device of this kind which will perform the work as nearly auto means for regulating the action of the cutting blades.

The invention also consists of the novel features of construction hereinafter fully described, pointed out in the claims and shown in the accompanyin drawings, in which Figure 1 is a side e evation of the complete machine, a drive belt being shown in section. Fig. 2 is an enlarged detail elevation, partly broken away, and parts being in section, showing cutting mechanism in position, a patternand blank being shown in dotted ines. Fig. 3 is a plan view of a rotatable table and of the cutting mechanism, a por tion of the table being broken away and parts of the frame and certain pins being shown in section. Fig. 4 is a sectional view on the line 4-4 of Fig. 2. Fi 5 is a detail perspective view of a pivoted rame and the V cuttlng mechanism carried thereby. Fig. 6

' is an'enlarged detail sectional view showing aportion of a rotatable table in section, and showing a transverse section through a casing having a sliding to said casing being carried by the table. ig. 7 is a detail sectional view of the line 77 of Fig. 6, and Fig. 8 is an enlarged perspective view of a pattern. Figs. 9, 1'0, 11, 12, and 13 are detail perspective views of parts carried by a swinging'frame detached therefrom. Figs.

raised position by a. coil spring 25.

plunger carries at its lower end, which pro 14 and 15 are detail perspective views of which mes es with a bevel 1pinion 6 carried s aft 7 upon the 1 upon the inner end of the outer portion of which is mounted loosely a pulley 8 driven by a plate 8. A clutch 9 is provided for the purpose of locking the shaft 7 to the pulley 8 and said clutch is operated by meansof an angled lever 10, operating rod 11 pivotally connectedto the end of the lever and shifted by a ivoted handle 12. The table 4 is also centr ly cutout as shown at 4 andin this cutout portion is loosely arranged a circular disk 13 which rests upon the top of the reduced portion 3 of the stand 7 ard 1, and remains stationar as thetable 4 The dis 13 ciirries an elongated platform 14 which is provided adjacent its opposite end with two upright posts 15 reduced at their ends to form upright projecting pins 16.

The frame 2 supports an angled Lbeam 17, the upper end of which overhangs the platform 14. Upon one side and in the an le of the beams is mounted a rotatable dis lr 18 to which is pivotally connected the u per end of a link 19, the lower end of w ich is pivotally connected to a foot treadle 20. There is also pivoted to the disk 18 a rod 21 which is also pivoted eccentrically to a pivoted cam 22 carried by the overhanging portion of the beam 17. Depending over this ortion of the beam is a casing 23in whic works a plunger 24 held normall in his JQCtS downwardly through the -cas' plate 26 which is raised at its ends an in the recesses works sprin pressed inwardly extending bolts 27 provided at their outer ends with pivoted thumb pieces 28. A. cooperating plate 29 carries upon its upper face keepers 30 which extend into the recesses of the plate 26 and which engage normally the bolts 27. By pressing upgn the lower ends of the thumb pieces 28, 1; bolts can bc-disengaged from the keepers and the plates 29 removed. The plate 29 carries adjacent each end a depending rod 31 which is orovidcd at its lower end with a foot piece or hoe 32. A pattern 33 is recessed longitudinally upon its sides adjacent the instc portion as shown at 34 and 18 provided wit 1 apertures 35 which receive the pins 16 of the osts 15. Guide plates 36 are arranged radia l' upon the table 4 and while said plates coulii each be constructed in one piece and inwardly angled, I have shown each of said plates as being formed in two sections, the uppermost extending inwardly as shown in Fig. 6. A- slidable casing 37 moves between thes plates being held against vertical movement by the uppermost sections and being held against lateral movement by the uppermost sections and by adjustin screws 36. The casing 37 is provided wit a plurality of transverse shafts 38 upon each of which is keyed a gear wheel 39 andabout which is placed. a coil spring 40 which is secured at one end to the casin and at the opposite end to the gear whee 39, said gear wheel being slidable on the shaft.

Adjacent each gear wheel is placed a leaf spring 41 fixed at its lower end and having a pro'ecting pin 41 a which is normally adapted to t within one of a number of suitable sockets formed in the side of the wheel as shown in Fig. 2. When the pins 41 are in engagement with sockets of the gear wheel 39, the said gear will be locked against rotation upon the shaft. The springs 41 are pushed outwardly and the pins disen aged frr the sockets and thegears unlocke by mean .l a

cam block 42 beveled at each springs. Thiscam lockis carried bya slidable.- top 43 of the casing 37, the said top being moved upon the casing and independent of movement of the casing by engagement of the ear wheels the under side of the top 43. A portion of the table 4 beneath the casing 37 is cut out as shown at 45 and in this cutout portion is a fixed shaft 46 which carries a geai wheel 47 which engages a rack bar 48 formed upon the under side of the casing 37. A coil spring 49 encircles this shaft and is fastened at one end to the table 4 and at the o po s1te end to the gear 47. The top 43 is hel in po sition upon the casing 37 by guide strips 50 and set screws" 50", the general construction being substantially the same as that of the guide plates 36, already described. At its inner end the casing 37 carries an inwardly bifurcated arm 51 in which is rojecting' rollers 5 which rollers engage 'tl fe sides of the platform 14 following said sides for a purpose which will hereafter appear.

The top 43 r'evious v described, carnes an upwardly an inwardly extending arm 53.

onzonta l mounted end so thu't it will enter between the gear wheels and the I 39 with the rack bar 44 carried j A frame 54 is pivotally mounted between the one free end 01' the arm 53 and the inner end of the top 43, and it will be obvious that as the arm 53 i ais'o carried by'this top, movement of the top upon the casing 37 will cause a corresponding movement of the frame 54.

t the casing it will be further remembered the.

37 is )lascd radially upon the table i and that t 10 top 43 has a longitudinal movement with respec! to said casing and consequently has a movement with respect to the table 4 upon a radial line of said table.

The lower portion of the frame 54 is formed of a horizontal block 55 which slides upon the top 43 being adjustable with respect to the main portion of the frame to which it is connected by a loose tenon and mortise joint I and by suitable adjusting screws 5 which work through suitable lugs carried respectively by the upright iortion of the frame 54 and the block 55. T e forward end of this block is also provided with a sliding bifurcated block 56 thereby forming projecting Li 5 movable in advance of the block 55 and c amped in their adjusted position by a set screw 58 which works through a slot 59 formed in the sides of the block 55, the block 56 being inserted and working within a suit able recess formed in the free end of the said block 55. Upon one side of the frame 54 is held an adjustable plate 60 which carries a finger 61, the said f'uiger being secured by screws to the outer face of the )late 60 and then being bent to pass beneath and transversely to said plate, the free end of the finger 61 being bent forwardly and extending upwardly to and upon the opposite side of the frame 54, as shown most clearly in Figs. and 5, where views of different portions of i the said finger are shown. a The plate 60 also carries presser feet 62 and 63, respectively, the upper ends of which overhang the top of the I p ate and the lower ends of which curve under the plate. Both of these feet are adjustable vertically and their lower ends coopcrate with certain cutters to be hereafter I referred to.

orkin adjustably. and vertical] u on the side 0 the late 60 o posite the rac et 63 is a cutter b ock 64 a usted with res ect to said late by an adjusting screw 64 w rich works t 'irough the overhan 'ng top ortion I of the bracket 63, and the lbwer cm of the j cutter block 64 carriesa downwardly and inwardly extending cutter 65 arranged ade- 1 cent to and transverse to the lower end of t c i bracket 63. A cutter block 66 provided with a cutter 67 is carried by a vertically sliding block 66. A cutter 68 extends upwardly from the block 55, the lower end of the bracket 62 forming a guard for said cutter. The shape and action of this cutter will be described more fully.

A spring 69 is secured at one end to the outer face of the plate 60 and is coiled between its ends, the free end resting upon a. pin 7 0 carried by the bracket 63, the said in also bearing upon an angled arm securcc to the bracket 62 and extending transversely across the bracket 63, and beneath the pin 701 Upon the opposite side of the frame 54, over the plate 61 is arranged two still springs 71, one end of each spring being firmly held in a bifurcated screw passed through the plate 60 while-the free ends oi'said springs ear upon pins 71", carried by the block 66 and 71? carried by an extension 74 of the block 62, said extension beingprovided with suitable vertical dove-tailed grooves in which the block 66 slides. An operating cam lever 72 is pivotally mounted upon the side of the frame 54 op osite the plate 60, the inner cam portion-of t e lever hearing when the lever is fted u wardly, upon a pin 72 carried by a vertica y movable link 73 secured to the extension 74. This extensionis provided with outwardly extending lugs 74 and a parallel lug 74* extends outwardly from one side of the block 66 and a threaded rod 75 nor-ks through both of said lugs, the lower end of thorod bearin u on the fm'wardly extending ortion of tire racket 61. Milled nuts 76 war upon the rod 75 above and below the lug 74, through which the rod 75 passes loosely. A strong lift spring 7? is secured at its up or end u on the back of the frame 54 and t e lower tree end of this spring rests against the end of the tenon of the block 55. A lever 7 2 normally rests in engagement with a sto pin 78. When this lever is thrown u ward y the action of its cam portion lifts t e link .73 thereby lifting the cutters 6b and 67 intriino )erative position.

It will be obvious that by running upward lv upon the threaded rod 75 the upper milled end 76. there will be no upward move ment of the cutter until the lug 74 comes into contact with said nut, the said rod passing loosely through the lug 74 and being threaded through the lug 74*. It will also be obvious that if the cutter 6.5 is given suliicient lead over the cutter or there will be no lilting movement of the last mentioned cutter when the lever 72 is lifted. Consequently either both or only one of the cutters may be thrown into .in-operative position by the lifting of said lever. This lever is lifted before the cilt ting operation commences and the table 4 starts its rotation"about the work with the lever 72 in uplifted position.

To automatically throw the lever down and permit the cutters to drop into operative position at exactly the proper time, I place 11 on the top 43 of the casing 37 a cam 79 which at the proper point of rotation oi the table engages a vertical movable foot 8U normally held. down by a spring 8] and work' ing through a bracket 82 carried by the beam 17. This foot pivotally connected to a lever which is pivoted between its ends and which. carries at the end opposite the foot 80, 9. depending bar 84 having a shoe 85 in position as it descends to strike the uplifted lever 72 and to throw the same downwardly. This places the cutters in operative position at exactly the proper position with res ect to e pattern upon which the work 138 been made. This astsures that thework of channeling and trimming which commenced at the proper point upon the sole will be correctly started without-regard to the relative position of the fi ame and the pattern when rotation of the table 4 commenced.

It will also be obvious from the drawings that the platform 14 above which the pattern is supported guides the cutting device about the said pattern, as the table 4 rotates and the roller 52 reaches a position upon the guiding platform 14 correspondit. to the heel or toe of the pattern and passes around the same, the casting 37 will be forced radially toward the periphery of the table and during this mov ment of the casing, rotation of the gear heel 47 will wind the spring 46 and upon completion of the heel or too turniru. movement, the unwinding of the said spring will cause the casing to move radially and inwardly. Ih a like manner the cover 43 will be caused to move downwardly and inwardly with respect to the center of the table by reason of engagement with the pattern 33 of the m vable portion 56 of the block 55 and as the pattern is recessed as shown at 34 adjacent the instep one lip of the block 56 will slide on the fac of the pattern which the other lip will project into the said recess thus permitting the cutter blades to operate at a point far. ther distant from the edge of thr. sole.

it will also be obvious that the sliding movement of the cover 43 upon the casing will also rotate the gear wheels l-Qthu. .sind ing the spring 40, the said gear wheels will be locked against rotation by the springs 41 until such springs have been moved out of e gagement with said gear wheels by the cam 42.

To lick lie top 43 in an inoperative positin, l rovide a lever 8l3 pivoted noon one s ;e of" the casing and which carries aliook S7 vii'lich engages apin SS-Which pin works through the longitudinal slot 89 cut in a side of the casing The lever S-" is thrown over from the position shown in Fig. 1 to that shown in Fig.3, and the book permits the pinto slide in the slot, which pin it will be understood has its inner end secured to the sliding top 43.

The angle arm secured to the presser foot and cxtendin past the presscr and lifts the last mentioned presser foot when the work is done. Ely regulating the position of the bifurcated b ock 56 the posifoot 63 engages the un erside of the pin 70 tion of the cutters with respect to the pat tern may be changed, as the block 56 can be moved so as to project more or less beyond starting the machine the shafts 38 are turned with a wrench, key or handle and the springs 40 connected to the gear wheels 39 are wound up.

What .1 claim is p l. in a device of the kind deselinemfl revolving table, means for holding work cen trally and fixedly with respect to the table, a radially movable casing in the table, a longitudinally movable cover in the casin an arm rarried b the casing, and adjustable cutters carried )y the arm and operating on the work.
